L Arginine is an amino acid that is considered ‘semi-essential’ or ‘conditionally essential’ due to the fact that it can not be synthesized in the body until close to adulthood. This is perhaps one of the most important supplements for the penis enlargement program due to its PROVEN ability and effectiveness in increasing nitric oxide levels in the blood and is why it is often found in male enhancement supplements.

It is commonly used by athletes to enhance performance and is considered even more effective when coupled with citruline. It also a substrate to form creatine, another vital nutrient for male enhancement and athletic performance. Deficiency of this amino acid may lead to impaired neuromuscular functions.

How Can L-Arginine Help To Enlarge The Penis?

The body uses this amino acid to produce nitric oxide. The more L-arginine it has, the more nitric oxide it can make. With more nitric oxide comes more blood flow and vascularity, especially in the penis. It is a simple and proven mechanism. Extensive research has confirmed this idea.

Arginine seems to enhance blood flow specifically in muscle groups that are stimulated or activated, including the smooth muscle of the penis.
